HOW TO TRIGGER IFC GPCM MODE

[Yangjk]

l have a custom board ls1043a, when I want to trigger the operation on nand flash control mode,I can operate  the  NAND Operation Sequence Start register( IFC_NANDSEQ_STRT).

Now I want to trigger the operation on GPCM control mode,which register should I operate?

My understanding in acknowledgement mode when CSORn[WGETA]=0(The access is a write, BCTL remains high for the whole duration) is as follows:

The timing settings of IFC_CSORn_GPCM[TRHZ] and IFC_GCR[BCTLD] are ignored(invalid).

Thank you for your answer, my understand :

if my LS1043 board wants to transfer data to external board , needs external board send signal on the external pin IFCTA_B . When LS1043 board receives this signal on the pin IFCTA_B, then transfer data to external board ?
